Hi Dennis
I am running centos 8.2 I start out with
[root@apollo-test ~]# omd versions
1.6.0p17.cre (default)
I backup the site, install p18 and update the site
[root@apollo-test tmp]# omd versions
1.6.0p17.cre
1.6.0p18.cre (default)
I then do an omd clean up to get rid of p17
[root@apollo-test tmp]# omd cleanup
1.6.0p17.cre Uninstalling
1.6.0p18.cre In use (by test). Keeping this version.
[root@apollo-test tmp]# omd versions
1.6.0p18.cre (default)
Now I try to restore the backup
[root@apollo-test tmp]# omd restore test /tmp/backup.tgz
You need to have version 1.6.0p17.cre installed to be able to restore this backup.
Is this a bug with CRE if you did not experience this with CEE?
